BF0040A12060 - CONTROL RELAY 4NO 120/60

Why Choose the BF0040A12060?

Engineered by Lovato, the BF0040A12060 is a robust control relay designed for dependable signalling and interlocking in industrial control circuits. It features an AC 60Hz, 120VAC coil and four normally open contacts, providing clear auxiliary switching across a 4‑pole platform. Installation is straightforward via screw fixing or 35mm DIN rail mounting. With a rated insulation voltage of 690 V and 6 kV impulse withstand, it suits panels demanding reliable, repeatable performance.

Built to endure, this unit offers 10 A Ith (IEC) and an exceptional mechanical life of 20,000,000 cycles. It operates from -50 to 70 °C and stores from -60 to 80 °C, with reliable performance up to 3000 m altitude and pollution degree 3. Terminals tighten to 1.5–1.8 Nm, and the device weighs 354 g. Conformity includes IEC/EN 60947-1/-5-1, UL 60947-1/-5-1, and CSA C22.2 n° 60947-1/-5-1 for assured compliance in UK and global panels.
